Abstract
The utility model provides a belt balance without a speed measuring sensor belonging to the field of dynamic weighing, which eliminates defect of weighing deviation of belt balance arising from inaccurate signals from a speed measuring sensor and provides a belt balance for production site of poor environment characterized in simple structure, strong practicality, lower cost and high accuracy. The utility model comprises a balance body (1), a connecting piece (2), a sensor (3), a weighing display (4) and a weighing supporting roller (5). An eccentric block (6) is positioned on an internal side of a cavity in the weighing supporting roller (5). The eccentric block (6) is moveably connected with the weighing supporting roller (5). Without a speed measuring sensor, the utility model accurately weighs materials on the belt and greatly reduces failure rate of belt balances.
Description
Technical field
The present invention relates to a kind of dynamic weighing weighing apparatus, particularly a kind of weigh belt scale.
Background technology
Belt conveyer scale generally all is equipped with LOAD CELLS, tachogenerator at present, weighing displaying controller, the signal that transmits according to LOAD CELLS and tachogenerator, obtain mass flow on the belt as calculated, but sensor all belongs to accurate rapid wear device, and the environment for use of belt conveyer scale is generally more abominable, very easily causes sensor to damage, particularly speed pickup can cause the weighing distortion owing to factors such as artificial cheatings, causes damage to enterprise; When belt conveyer scale was used to prepare burden, the weighing distortion also can influence the quality of batching back product.
Summary of the invention
The invention solves owing to speed pickup transmits the inaccurate technical matters that makes the belt conveyer scale metering distortion of signal, provide a kind of simple, practical, low-cost, high belt conveyer scale of accuracy in particular for the more abominable production scene of metering environment.
The present invention is achieved by the following technical programs.
Non-tachogenerator belt conveyer scale comprises scale body 1, web member 2, sensor 3, weighing displaying controller 4, weighing carrier roller 5, and the cavity inboard of described weighing carrier roller 5 is provided with eccentric block 6.Described eccentric block 6 flexibly connects with weighing carrier roller 5.Described eccentric block 6 can be fixedlyed connected with weighing carrier roller 5, and the length of described eccentric block 6 can equate with the length of weighing carrier roller 5.The length of described eccentric block 6 can be less than the equal in length of weighing carrier roller 5.The weight of described eccentric block 6 is 1 with the ratio of the deadweight of weighing carrier roller 5: 5---1: 3.
The present invention has realized under the situation of Speedless sensor, to transmitting the accurate metering of mass flow on the belt, greatly reduces the failure rate of belt conveyer scale, makes the belt conveyer scale body structure simple, and working service is convenient.

Instantiation
Embodiment 1: non-tachogenerator belt conveyer scale, comprise scale body 1, weighing framework 2, sensor 3, secondary instrument 4, weighing carrier roller 5, and the cavity inboard of described weighing carrier roller 5 is provided with eccentric block 6.Described eccentric block 6 is by bolted with weighing carrier roller 5.The equal in length of the length of described eccentric block 6 and weighing carrier roller 5.Weight of material on the belt is passed to secondary instrument 4 by weighing carrier roller 5 and weighing framework 2 with weight signal, simultaneously because the cavity inboard of weighing carrier roller 5 is provided with eccentric block 6, make carrying roller 5 off-centre, sensor 3 will receive clocklike sinusoidal wave weighing-up wave when it rotates with belt, secondary instrument just can calculate the speed of belt by counting, and then draws the mass flow that belt claims.
Embodiment 2: weighing carrier roller 5 of the present invention patches with being connected to of eccentric block 6 and is connected, and can be convenient for changing the eccentric block 6 of Different Weight and shape like this according to different belt conveyer scale specifications and mass flow.
Embodiment 3: weighing carrier roller 5 of the present invention is welded to connect with being connected to of eccentric block 6,
Embodiment 4: the ratio of the weight of eccentric block 6 of the present invention and the deadweight of weighing carrier roller 51: 5 the most.
Embodiment 5: the weight of eccentric block 6 is preferably 1: 3 with the ratio of the deadweight of weighing carrier roller 5.
Claims (6)
